You can use senderbase statistics to see if there is a huge increase in email
activity from the IP address under consideration.
For example, if you visit
http://www.senderbase.org/search?searchString=204.13.69.220
It says that on average the machine sends 10^2.9 emails per day. In the last
30 days, it sent 10^3.6 emails per day. Last day (ie yesterday) it sent
10^4.9 emails. The trend clearly indiciates that there has been an increase
in email activity which might correlate with the machine being a zombie.
This is not a fool proof test. But I have seen people being referred to this
website on spamcop forums, news groups.
